' To vall whom t may concern:

Nashin'gton, and State of Iowa,

Be it .known that I, CHARLES V. CRULL,

a citizen of the United States of America,

and aV resident of Washington,

i Vments-inv Hog-Waterers, of'whieh the'folf sert their heads when they specification.

lowing'is a full and clear type of This invention "relates to Vthat animal drinking this tankbeing so arranged with respect to the drinking-bowl l or trough that, as the water is removed from the latter, an additional supply will be delivered thereto from the supply-tank to maintainthe level of the water in the drinking-trough at a Ypredetermined point, the feed of the water taking place -in accordance with the well-known hydrostaticflaw, as more fully. hereinafter set forth.

In the drawings` v Figure l is a vertical sectional view;

Figs.V 2l and 3' are horizontal Vsectional views taken on lines 2 and 3, respectively, of-Fig. 1.

Referring to thel drawings by referencecharacters, a designates a circular drinkingpan or trough which is supported at its annular edge ona cylindrical casing this casing being provided with a bottom-plate c which, together with the trough, forms a lamp-'receiving chamber, the lamps being designated by the letters: d. The'vertical wall and the drinking-trough are supported by a series of vertical wooden posts e beveled at their upper ends to fit-against the tapered side-wall of the trough.

Supported upon the pan is a water-supply tank annular in cross-section at its` upper part and provided at its lower part`that is, in the zone adjoining the drinking-fountainwith a pair of oppositely-arranged ndentations g into which the animals may inreaeh into the trough to drink therefrom. Surrounding the tank j is a jacket 7L which forms virtually an extension of the lower easing wall b and which forms, in conjunction with the wall of the tank, a warm-air space. To per- Init the heated air from the heating chamber below the trough to ascend into the space between the jacket and the tank-wall, I provide the annular drinking-trough with a series ofvertical flutes z' to form vertical Vfountain or trough in which an overhead supply-tank 1s employed,

` pends into the water ing-trough. The filling-tube p extends down flues leading from theV heating chamber into the -jacket space. Coincidental with each of the drinking` pockets g, there is provided a `shield y' which extends inwardly and bridges the heating jacket space, so as to thereby prevent'the heated air and products of 'combustion from escaping' at these points. These shields j arefastened tothe wall of thejacket 7i and extend inwardly into each ofthe recesses g.

The jacket edge is provided with a topplate it which at its center isl provided with an opening which is adapted to be closed by a suitable pivoted plate Z, Vthe edge ofthis opening being provided Vwith a depending "flange` m which engages over an upstanding :flange n carried by a top-wall o covering the top of the supply-tank f. rllhe height of the supply-tank f issuch that an aniullar space is provided between its top-wall 0 and the top-wall la of the jacket, and it will be observed that the two flanges fm and aforni a division wall or baffle-plate between the heating-, 'pace and the central opening in the top-plate.

The top-wall 0 is dished downwardly to form in effect a funnel, the apex ot which is connected to the upper open end of a vertical filling-tube p, whose upper end is protected by a piece of wire gauze l] to prevent foreign bodies entering the filling-tube,

Inside of the annular flange a on the topwall" is provided a petcock r.

Depending centrally from thefbottom-wall of the supply-tank is a tube upper end to the water in the tank and partly closed at its lower side by a cap-plate t, this tube s' being of' such length that it deconfined in the drinkinto this tube to a point in close proximity to the cap 25. The cap t is provided with a. hole in its center and surrounding this hole is a depending flange u which forms a conical valve-seat; and adapted to seat against this valve-seat is a conical valve fu affixed to the lower end of the rod w which extends up through the filling-tube and is provided with a handle a: at its upper end which lies in the funnel-chamber so as to be conveniently rea ched when the top-plate Z is slid to one side. The valve-rod is provided with a stop-button y which, when the valve is open, rests upon the gauze disk g.

It will be observed that when the lamps Patented 0611.21, 1919.`

s open at its llO likely to become froZen. By

' charge opening to or other heating devices are in' use, the hot air and products of combustion will keep the water in the pan warm as well as the water in the supply-tank, and thus prevent freezing in cold weather. When the water rises in the pan, it seals the lower end of the discharge-tube s and thus prevents any more water flowing into the pan from theV in accordance with the wellknown hydrostatic law. As the water in the drinking-trough is removed, additional water will flow thereinto from the supplytank, so as to thereby maintain the level in the drinking-trough at the desired predetermined point. When it is desired to rell the supply-tank, the valve fu is closed by pulling-up on the rod fw, then the petcock r is opened, and the additional water poured into the central funnel-chamber. Vh'en the desired quantity of water is thus poured into the tank, the petcock fr is closed and the valve U is opened, whereupon the normal automatic feed is again put into action. Surrounding the depending discharge-tube s a cylindrical wall ,e which is affixed airtightly to the bottom of thetank and depends into the water space of the trough, thereby forming an annular air-tight chamber whose lower end is openV to the water in the trough, so that, as the water fills the trough, it will rise in this annular chamber and compressv the air trapped therein. The air thus trapped forms an annular insulating body around the discharge from the water-tank. discharge from the tank is subjected to the atmospheric temperature because of the drinking pockets g. In cold weather, the air at atmospheric temperature entering supply-tank,

through the drinking pockets g would come in contact with this comparatively narrow column of water, which would, therefore, be providing the annular' wall or flange e by which'the body of air is trapped, a dead-air or insulating medium will be provided' around the disprotect the same.

,HIt will be observed that a feature of iin- Copies of this patent may `Yne obtained for At this point the water in the Y portance in vmy apparatus is that the operation of filling the supply-tank may be en'- tirely controlled from the upper end of the tank, thereby avoiding the necessity of the attendant putting his hands down in the water in the trough, an operation which is inconvenient, especially in cold Vweather. This is accomplished a filling-funnel and filling-tube, but also by arranging the discharge-valve vV so that it may be operated from the top of theV apparatus. ,Y Y

The nature and scope of the invention having been thus indicated and its preferred embodiment having scribed, what is claimed as new is:

1. In combination with a trough and a supply-tank surmounting same, a jacket surrounding the supply-tankand means for heating the air between the jacket and the tank, said tank and said jacket'being provided with separated top-plates, annular flanges on said top-plates, said flanges cooperating to form the side-wall of a fillingfunnel, said top-wall of the supply-tank inclining downwardly and inwardly in substantially the form of a funnel toward a central filling opening.
